Changes with Slimmelezer and Aidon 6534

[MrGlad8]

First of all, thank a lot for this code. Helped me a lot! I bought Slimmelezer Plus for my Aidon 6534 just to realise afterwards that the energy meter doesn't follow the standard protocol. But with your p1reader-code with some modifications I got it to to work. Thanks to Skracke on byggahus forum and jsuanet at HA forums. Let me show you how I got it to work! The changes I did in order to get the Slimmelezer Plus to work with my Aidon 6534 meter was:

In file "p1reader.h" =

• define BUF_SIZE 50 to #define BUF_SIZE 60

• In every place where "readBytes" occurred I changed to "Serial.readBytes". Was like in 5-6 places, I used the search for "bytes".
• Also in some placed there was "readBytesUntil" and that I changed to "Serial.readBytesUntil".

And in file "p1reader.yaml" I changed:

• tx_pin: TX to tx_pin: D8
• rx_pin: RX to tx_pin: D7
• I also changed the name from "electricity_meter" to "slimmelezer". Not sure why but jsuanet on the forums said OTA update would fail otherwise. I did the change and have not had any problems yet.
• Also changed board from "nodemcu" to "d1_mini"
• I also added:
• web_server:
• port: 80
• In order to be able to surf into the IP number of my Slimmelezer.
• And lastly I added to the sensor "Cumulative Active Import"
• state_class: total_increasing
• device_class: energy
• So that it could be used as an energy-meter in HA.

I hope this can help someone else in my position with a Slimmelezer Plus and a Aidon 6534 energy meter that doesnt follow standard protocol :)

I have found some information about the meter but my coding skills are none so a would appreciate some help.

Interface desription from skekraft: https://www.skekraft.se/wp-content/uploads/2021/03/Aidon_Feature_description_RJ45_HAN_Interface_EN.pdf

and some example to read the data https://github.com/OlleRatu/han-rj45/blob/main/HAN_aidon_rj45_example/han.py
